Celebrity chef Michael Mina takes on Japanese cuisine (with partner Ken Tominaga) at this high-end izakaya in Harbor East's Four Seasons (but accessed via a separate entrance on Aliceanna Street) that serves classic dishes from a robata grill and a sushi bar, washed down with a world-class sake selection; the rough-wood tables, bamboo ceiling and privacy panels keep it casual even though there's a sleek sheen to everything.
